This is a worth while product for the homeowner who cuts on the weekend or a few times a year. I have a bench mounted sharpener that is now collecting cobwebs. This sharpener is well made and about 1/2 the price of the identical branded one.
About 5 minutes to sharpen a blade. This saves time over bench sharpeners. It knocks down the rakers as you file, another time saver. It does a better job sharpening than my bench mount.
Misleading marketing of the product leads one to believe this is ditra. I'm worried the floor wont last long. I feel i should just throw it away in the trash where it belongs.
